Heart rate variability can clarify students' level of stress during nursing simulation

Too stressed to think? A scoping review of the literature for healthcare educators utilising high acuity clinical scenarios

BACKGROUND

The practise of paramedicine can be highly stressful particularly where urgent lifesaving decisions need to be made. Traditionally, educators have adopted the approach of placing students in simulated stressful situations as a way of learning to cope with these challenges. It is unclear from the literature whether traditional stress inoculation enhances or hinders learning. This scoping review aims to identify and examine both the peer-reviewed and grey literature reporting physiological stress responses to high-acuity scenarios in paramedicine and cognate healthcare disciplines.

METHODS

Adhering strictly to JBI Evidence Synthesis Manual for conducting a scoping review, medical subject headings and areas, keywords and all other possible index terms were searched across EBSCOhost (Medline, CINAHL and APA PsycInfo), Scopus and, PubMed. English language articles both published (peer-reviewed academic papers, reports and conference proceedings) and unpublished (grey literature, Google Scholar reports) were included, and publications citing retrieved articles were also checked.

RESULTS

Searches performed across five electronic databases identified 52 articles where abstracts indicated potential inclusion. From this, 22 articles which reported physiological or psychophysiological responses to stressful scenario-based education were included.

CONCLUSION

This review identified that an acceptable level of stress during simulation can be beneficial, however a point can be exceeded where stress becomes a hinderance to learning resulting in underperformance. By identifying strategies to moderate the impact of acute stress, educators of paramedic and other healthcare students can utilise high-acuity clinical scenarios to their andragogical armamentarium which has the potential to improve real-world clinical outcomes.

Untapped resource: the simulation-based healthcare environment as a means to study human stress

The effects of 'stress' within the healthcare professions are wide-reaching, not least of all within the field of simulation-based healthcare education. Whilst this popular method of experiential learning offers a 'safe space' for participants to develop their skillset, it also has a more surreptitious action; namely, the incubation of simulation-related stress. Currently, research concerning the complex relationship between stress, learning, and performance is ambiguous, leaving fertile ground for simulationists to debate what level of stress is appropriate for an optimised educational experience. In this narrative review, we examine the human response to stress and outline the various methods that have been used by researchers to measure stress in a quantifiable and standardised way. We then provide a brief overview of simulation-based healthcare education before describing why stress responses have been of interest to healthcare educationalists for some time. Finally, we outline how simulation education environments might provide an ideal environment for studying the human response to stress generally, with ramifications extending beyond the field of medical education.

Simulation-based education as a provider of fieldwork insights - experiences of ambulance nurse specialist students

BACKGROUND

Medicine is facing a global shortage of nurses, including those with postgraduate education. One suggested educational method for undergraduate and postgraduate education, such as specialist ambulance nurse education, is simulation-based education (SBE). The implementation of SBE is motivated, in part, by the desire to attract and retain students, but also to contribute to student learning. Consequently, the use of SBE is increasing in specialist ambulance nurse education. The aim of this study was to explore how specialist ambulance nursing students experience SBE.

METHODS

This qualitative survey study involved the collection of study data using a purposefully designed, paper-based survey comprising five open-ended questions that required participant free-text answers. The answers were analysed using inductive content analysis and searching for descriptions of the participants' experiences. The survey was presented to 35 specialist ambulance nursing students.

RESULTS

The results are presented in two themes: SBE as learning and SBE as an educational method. Participating in SBE during the programme provides students with a realistic understanding of their future profession and its expected demands. The learning experience disregards prior work experience in ambulance services.

CONCLUSIONS

Based on the findings, conclusions are that SBE is an appreciated educational method among nursing students, regardless of their prior experience in the field of prehospital care. To some extent, this differs from previous research findings related to this subject. Furthermore, SBE contributes to the provision of field work insights, preparing the ambulance nurse specialist students.

ACACIAS 1: The physiological and subjective impacts of high fidelity simulation of the breaking of bad news

STUDY OBJECTIVE

Breaking bad news (BN) is difficult and necessitates targeted training. To be effective, training may call for High Fidelity Simulation (HFS). This prospective study was conducted to objectively assess the impact of HFS as a tool conducive to the development of clinical competence in situations involving the delivery of bad news.

METHODS

This feasibility study was conducted from January to May 2021 and included students in medical oncology and digestive surgery. The subjective and objective impacts of HFS were evaluated by means of a self-administered questionnaire and a wristband, Affect-tag, which recorded several indicators: emotional power (EP), emotional density (DE) and cognitive load (CL) in students undergoing training.

RESULTS

Forty-six (46) students with a median age of 25 years (21-34 years) were included. While the participants were effectively and emotionally involved in the HFS training, they were not completely overwhelmed by their emotions, a possible occurrence in this type of program. After two training programs, the students presented with lower EP (P<0.001) and higher DE (P=0.005), while their CL remained stable (P=0.751). The information given in the self-administered questionnaires and the evaluations by outside professionals (actor, nurse, psychologist…) highlighted improved skills.

CONCLUSION

Taking into account the emotional parameters observed and the questionnaires collected, HFS can be considered as a suitable and effective tool in the breaking of bad news.

Role of peer learning and self-efficacy in parasympathetic activity during the simulation learning process in nursing students

AIMS

This study aimed to investigate the stress level, including parasympathetic nervous activity, of students engaged in peer learning during simulations and the role of self-efficacy.

DESIGN

Observational-comparative study.

METHODS

The participants were 76 nursing students who were asked to evaluate a stable postoperative patient in Scene 1 and the same patient bleeding in Scene 2. In each scene, the students engaged in phases of repeated individual observations of the patient and discussions with peers. We compared each participant's parasympathetic activity during each observation in Scenes 1 and 2. Furthermore, the self-efficacy score before the simulation was used to divide the participants into 3 groups, and the self-efficacy and parasympathetic activity during the simulation were analysed.

RESULTS

The participants' parasympathetic activity decreased in both scenes with each phase of repeated observation. Two-way repeated-measures analysis of variance showed no statistically significant difference in parasympathetic activity during simulations among the three self-efficacy groups.

A Systematic Review of Heart Rate Variability as a Measure of Stress in Medical Professionals

Understanding the physiological effects of responding to crises is a critical component in understanding how to manage and prepare medical professionals to be crisis responders. Heart rate variability (HRV) is the variation in rate between a succession of R-R intervals. This variation is not only affected by physiological processes such as respiration or metabolic rate but is also directly controlled by the autonomic nervous system. As such, heart rate variability has been proposed as a noninvasive tool to measure the physiological stress response. The aim of this systematic review is to consolidate heart rate variability literature in the context of medical emergencies to determine if heart rate variability changes predictably from baseline when responding to medical crises. This may demonstrate utility as an objective, noninvasive measure of stress response. A systematic literature review of six databases yielded 413 articles, 17 of which met our inclusion criteria of being written in English, measuring HRV in healthcare providers, and measuring HRV in real or simulated medical resuscitations or procedures. Articles were then analyzed using the Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) scoring system. Out of the 17 articles reviewed, 11 demonstrated statistically significant results showing heart rate variability responding in a predictable manner to stress. Three articles utilized a medical simulation as the stressor, six used medical procedures, and eight used medical emergencies encountered during clinical work. Overall, a predictable trend in heart rate variability metrics of standard deviation from the mean value of normal-to-normal (N-N) intervals (SDNN), root mean square of the successive differences (RMSSD), mean number of times per time interval in which the change in successive normal sinus (N-N) intervals exceeds 50 ms (PNN50), low frequency % (LF%), and low-frequency-to-high-frequency ratio (LF/HF) was observed when responding to stress. This systematic literature review showed that heart rate variability among healthcare providers responding to stressful scenarios follows a predictable pattern of change and expands our understanding of the physiology of stress in healthcare providers. This review supports the use of HRV to monitor stress during high-fidelity simulation to ensure that appropriate physiological arousal is achieved during the training of medical personnel.

The Impact on the Stress-Associated Autonomic Response of Physiotherapy Students Receiving Interferential Current in an Electrotherapy Training Session

Electrical currents are didactic contents widely applied in the training of physiotherapy students, but the treatment is considered a stressful situation for both the patient who receives it and the student who applies it. The aim of this study was to evaluate the stress-associated autonomic response of physiotherapy students receiving interferential current by measuring and analysing heart rate variability. An observational case-control study was conducted. Ninety healthy male volunteers, all physiotherapy degree students, were enrolled while attending laboratory practice during the 2020-2021 academic year. Participants were randomly allocated to a sham electrotherapy group (44 subjects), in which heart rate variability was recorded for 10 min, both at rest and during the application of sham technique on the lower back (10 min), and an electrotherapy group (46 subjects), applying the same procedure with the electrical current flowing. Outcome measures included baseline (seated position) and postintervention (prone position) time domain parameter, diameters of the Poincaré plot 1 and 2, stress score, and sympathetic/parasympathetic ratio. The sham electrotherapy group exhibited significant increases in time domain parameter (p = 0.027) and diameters of the Poincaré plot 1 (p = 0.032), with a small effect size (d ≤ 0.5). The electrotherapy group exhibited significant increases in time domain parameter and diameters of the Poincaré plot 1 and 2 (p < 0.001) and decreases in the stress score and sympathetic/parasympathetic ratio (p < 0.001), with a large effect size (d > 0.8) other than for the time domain parameter (d = 0.42), indicating increased parasympathetic and decreased sympathetic activity. After interventions, there were significant differences between groups in diameters of the Poincaré plot 2 (p < 0.001), stress score (p = 0.01) and sympathetic/parasympathetic ratio (p = 0.003), with moderate effect size (d > 0.5). The application of the interferential current technique produces stress-associated autonomic response characterized by greater parasympathetic activity and decreased sympathetic activity. Further studies are needed to determine possible adverse effects.

A Review of AI Cloud and Edge Sensors, Methods, and Applications for the Recognition of Emotional, Affective and Physiological States

Affective, emotional, and physiological states (AFFECT) detection and recognition by capturing human signals is a fast-growing area, which has been applied across numerous domains. The research aim is to review publications on how techniques that use brain and biometric sensors can be used for AFFECT recognition, consolidate the findings, provide a rationale for the current methods, compare the effectiveness of existing methods, and quantify how likely they are to address the issues/challenges in the field. In efforts to achieve the key goals of Society 5.0, Industry 5.0, and human-centered design better, the recognition of emotional, affective, and physiological states is progressively becoming an important matter and offers tremendous growth of knowledge and progress in these and other related fields. In this research, a review of AFFECT recognition brain and biometric sensors, methods, and applications was performed, based on Plutchik's wheel of emotions. Due to the immense variety of existing sensors and sensing systems, this study aimed to provide an analysis of the available sensors that can be used to define human AFFECT, and to classify them based on the type of sensing area and their efficiency in real implementations. Based on statistical and multiple criteria analysis across 169 nations, our outcomes introduce a connection between a nation's success, its number of Web of Science articles published, and its frequency of citation on AFFECT recognition. The principal conclusions present how this research contributes to the big picture in the field under analysis and explore forthcoming study trends.

Nursing students' perceived stress, self-efficacy, control and evaluation of a course in systematic clinical observation, physical assessment and decision-making: An observational study in Norway

AIM

Simulation-based nursing education interventions have a strong educational effect on psychomotoric skills, but students may experience physiological stress and anxiety during simulation. The aims of this study were to explore (1) nursing students' perceived stress, self-efficacy, control and evaluation before and after simulation as part a structured course in physical assessment, (2) whether factors such as gender, age or previous work experience were associated with perceived stress during simulation and (3) nursing students evaluation of the course.

DESIGN

An observational, cross-sectional study before and after simulation and a course in physical assessment.

METHODS

We utilized "the Self-Assessment Manikin for measuring emotion" before and after simulation, a questionnaire to identify symptoms of stress after simulation, and a questionnaire to evaluate the physical assessment course.

RESULTS

A total of 59 students participated. Students perceived stress before simulation but reported a lower degree of activation, a more positive mood, increased feeling of control and self-efficacy after the simulation. They also felt more secure about their assessments. Even though students reported of several symptoms of stress before simluation, the course increased students' self-reported competence and feeling of security.

Taking the pulse of a classroom with a gamified audience response system

BACKGROUND AND OBJECTIVE

This paper presents an empirical study of a gamified mobile-based assessment approach that can be used to engage students and improve their educational performance.

METHOD

A gamified audience response system called G-SIDRA was employed. Three gamification elements were used to motivate students in classroom activities: badges for achievements to increase engagement, points to indicate progression and performance in the subject and ranking for promoting competitiveness. A total of 90 medical students in a General and Descriptive Anatomy of the Locomotor System course were taught using G-SIDRA in the academic year 2019/2020. Smart bracelets were configured to collect heart rate measurements from 30 students with the aim of evaluating the impact of the gamification elements. The control group consisted of a sample of 110 students enrolled on the same course in the academic year 2016/2017 using non-gamified SIDRA.

RESULTS

Statistically significant differences were found between multiple choice questions (MCQ) scores obtained by using SIDRA and G-SIDRA in the four experiments (U = 1.621,50, p < 0,01 for Exp1; U = 1.950,00, p < 0,01 for Exp2; U = 955,00, p < 0,01 for Exp3; U = 2.335,00, p < 0,01 for Exp4). In the students' final exam grades, statistically significant differences between students that used G-SIDRA as opposed to SIDRA (T(157) = 3.992; p = 0.044) were obtained. Concerning gamification elements, statistically significantly differences were found in comparing the pulse increases after and before the badge event in the four experiments (U = 2.484,00, p = 0,038 for Exp1; U = 2.109,50, p = 0,046 for Exp2; U = 1.790,50, p = 0,025 for Exp3; U = 1.557,0, p = 0,048 for Exp4). However, there are not statistically significant differences between the pulse increases after and before the ranking event in the four experiments. In a 5-point Likert-type scale, the students expressed satisfaction with G-SIDRA (M = 4.552) and thought the system helped to better understand both theoretical and practical concepts (M = 4.092). Their global assessment of the G-SIDRA platform was 4.471.

CONCLUSIONS

Of the three gamification elements used in the study, only badge has an effect on heart rate. Better student responses and academic performance were achieved when using G-SIDRA. Nevertheless, more research is required to evaluate the impact of the gamification elements on the motivation, engagement and performance of students. Physiological measures are promising approaches for gamification elements evaluation.

Use of saliva stress biomarkers to estimate novice male endoscopist's stress during training in a high-end simulator

OBJECTIVE

Simulated endoscopic training can be challenging and stressful for the novice trainee. The absence of a reliable stress detection method during simulated endoscopic training makes estimating trainees' mental stress difficult to quantify. This study concomitantly measures the responses of four saliva stress biomarkers and compares them to the video score (VS) achieved by novice endoscopists in a reproducibly stressful simulation environment.

METHODS

Thirty-six male endoscopy naïve surgery residents were enrolled. After an orientation phase, a saliva specimen was collected for cortisol (sC), alpha-amylase (sAA), Chromogranin A (sCgA), and immunoglobulin A (sIgA) measurements (baseline phase, BL). Thereafter, the simulation exercise phase (E) started, practicing in the Fundamentals of Endoscopic Surgery Skills module (GI-Bronch Mentor). Immediately after, a second saliva sample for measuring the above-cited biomarkers was collected. The whole experiment was videotaped, and the VS was calculated. The percentage (E-BL)_diff of each of the four saliva biomarkers was calculated and examined for correlation to VS.

RESULTS

sCgA_diff showed the best correlation with VS, followed by sAA_diff.

CONCLUSIONS

sCgA and sAA, are saliva stress biomarkers that are easy to collect non-invasively and showed the best correlation with novice endoscopist's performance in our simulation setting, and therefore, they could be used for monitoring stress.

Bispectral Index Alterations and Associations With Autonomic Changes During Hypnosis in Trauma Center Researchers: Formative Evaluation Study

BACKGROUND

Previous work performed by our group demonstrated that intermittent reductions in bispectral index (BIS) values were found during neurofeedback following mindfulness instructions. Hypnosis was induced to enhance reductions in BIS values.

OBJECTIVE

This study aims to assess physiologic relaxation and explore its associations with BIS values using autonomic monitoring.

METHODS

Each session consisted of reading a 4-minute baseline neutral script and playing an 18-minute hypnosis tape to 3 researchers involved in the BIS neurofeedback study. In addition to BIS monitoring, autonomic monitoring was performed, and this included measures of electromyography (EMG), skin temperature, skin conductance, respiratory rate, expired carbon dioxide, and heart rate variability. The resulting data were analyzed using two-tailed t tests, correlation analyses, and multivariate linear regression analyses.

RESULTS

We found that hypnosis was associated with reductions in BIS (P<.001), EMG (P<.001), respiratory rate (P<.001), skin conductance (P=.006), and very low frequency power (P=.04); it was also associated with increases in expired carbon dioxide (P<.001), skin temperature (P=.04), high frequency power (P<.001), and successive heart interbeat interval difference (P=.04) values. Decreased BIS values were associated with reduced EMG measures (R=0.76; P<.001), respiratory rate (R=0.35; P=.004), skin conductance (R=0.57; P<.001), and low frequency power (R=0.32; P=.01) and with increased high frequency power (R=-0.53; P<.001), successive heart interbeat interval difference (R=-0.32; P=.009), and heart interbeat interval SD (R=-0.26; P=.04) values.

CONCLUSIONS

Hypnosis appeared to induce mental and physical relaxation, enhance parasympathetic neural activation, and attenuate sympathetic nervous system activity, changes that were associated with BIS values. Findings from this preliminary formative evaluation suggest that the current hypnosis model may be useful for assessing autonomic physiological associations with changes in BIS values, thus motivating us to proceed with a larger investigation in trauma center nurses and physicians.

Effectiveness of Health Guidance Simulation in Community Settings for Public Health Nursing Students: A Preliminary Study

Introduction

Simulation-based learning is a relatively new concept in public health nursing education, and little is known about the efficacy of this approach for teaching of health guidance. Objective: The aim of this study was to evaluate the effectiveness of health guidance simulation in community settings for public health nursing students.

Methods

Using a pre/post-test design, 29 public health nursing students in their third year participated in a high-fidelity simulation program with standardized patients. We developed six scenarios on health guidance for three themes (mother and child, tuberculosis, and adult occupational health) and practice guidelines for the standardized patients to act and assist in understanding of the purpose of the course. Data were collected at baseline and after the simulation sessions through evaluation sheets that the students placed in a designated box on campus. Changes in the level of self-confidence of the students were evaluated based on the “practical skills required for public health nurses and achievement level at graduation” of the Ministry of Health, Labor and Welfare, and the skills in the minimum requirements for public health nurse education defined by the Japan Association of Public Health Nurse Educational Institutions.

Results

The total score for self-confidence and the mean self-confidence scores for health guidance skills for mother and child, tuberculosis, and adult occupational health nursing were significantly higher post-test compared to pre-test (p < 0.001).

Conclusion

These results indicate that high-fidelity simulation focused on health guidance in community settings can bridge the gap between theoretical knowledge and practice of students.

Stress and anxiety in nursing students between individual and peer simulations

BACKGROUND

The use of high-fidelity simulation practice as an educational tool is becoming increasingly prevalent in nursing education. Despite the learning effects of simulation practice, students have been shown to experience high levels of stress and anxiety during simulation. In recent years, peer learning has been defined as an acquisition of knowledge and skills through active support and support among equal or equal peers and has been shown to be an effective educational intervention for clinical health science students.

AIM

The purpose of this study was to incorporate peer learning into simulation learning and to clarify the differences between stress and anxiety during personal and peer simulations.

METHOD

Third-grade undergraduate students in a four-year course at two nursing universities participated in this study. In this study, the simulated patient was a 53-year-old man who had undergone gastrectomy for the treatment of gastric cancer. The scenario was that the patient had completely recovered consciousness in the operating room, and his tracheal tube had been removed one hour before the students examined him. Stress while simulation training was evaluated with heart rate variability. Anxiety was evaluated by the STAI after the simulations were complete.

RESULTS

Personal simulation practice (personal group; n = 50) and peer simulation practice (peer group, n = 59) was conducted. The personal group included 7 male students, and the peer group included 12 male students; the difference in male proportion was not significant. At the first patient assessment phase, stress of heart rate variability components at the peer group significantly increased relative to that of the personal. In addition, the personal had a significantly higher state anxiety score after simulation than the peer.

CONCLUSION

This study shows that in the face-to-face scene involving vital sign measurements, the presence of peers did not objectively alleviate stress.

Reliability and validity study of the Spanish adaptation of the "Educational Practices Questionnaire" (EPQ)

The Educational Practices Questionnaire is an instrument for assessing students perceptions of best educational practices in simulation. As for other countries, in Spain, it is necessary to have validated rubrics to measure the effects of simulation. The objective of this study was to carry out a translation and cultural adaptation of the Educational Practices Questionnaire into Spanish and analyze its reliability and validity. The study was carried out in two phases: (1) adaptation of the questionnaire into Spanish. (2) Cross-sectional study in a sample of 626 nursing students. Psychometric properties were analyzed in terms of reliability and construct validity by confirmatory and exploratory factor analysis. The exploratory and confirmatory factor analyses showed that the one-dimensional model is acceptable for both scales (presence and importance). The results show that the participants' scores can be calculated and interpreted for the general factor and also for the four subscales. Cronbach's alpha and the Omega Index were also suitable for all the scales and for each of the dimensions. The Educational Practices Questionnaire is a simple and easy-to-administer tool to measure how nursing degree students perceive the presence and importance of best educational practices.

The effect of clinical simulation assessment on stress and anxiety measures in emergency care students

Background

Clinical simulation has become widespread as a training and assessment tool across a range of health professions, including emergency care. As with any form of assessment, simulations may be associated with stress and anxiety (“distress”) which may have a negative effect on student performance if demands required by the simulation outweigh the available resources. This study aimed to assess the effect of participation by students in an emergency care simulation on an objective measure of stress and a subjective measure of anxiety.

Methods

Heart rate variability (HRV) and scores from a validated state anxiety instrument (the State-Trait Anxiety Inventory) were assessed in 36 emergency medical care students participating in scheduled simulation assessments. Data recorded during a resting control period were used for comparison.

Results

HRV variables showed changes in the simulation assessment group suggesting decreased variability and parasympathetic withdrawal, however these were not significantly different to control. Heart rate in the simulation assessment group increased significantly (73.5/min vs. 107.3/min, p < 0.001). State anxiety scores increased significantly both before (33.5 vs. 49.1, p < 0.001) and after (33.5 vs. 60, p < 0.001) the simulation assessment, compared to control. No linear relationship was found between any HRV variables and anxiety scores.

Conclusion

Participating in an emergency care simulation assessment significantly elevated levels of anxiety in a group of 36 students, however an objective measure of stress did not identify changes significantly different to those at rest, with the exception of heart rate. The high levels of anxiety documented before and after simulation assessments may have a negative effect on performance and require further investigation.
